Investor Lawsuits Target ODDITY Over Ad-Algorithm Disruption as Lead-Plaintiff Deadline Nears

Overview

• Pomerantz filed a federal securities class action in the Southern District of New York, docketed as 26-cv-02046, for investors who bought ODDITY shares from February 26, 2025 to February 24, 2026.
• Bronstein, Gewirtz & Grossman and Berger Montague also announced actions and are recruiting investors, with a May 11, 2026 deadline to seek lead-plaintiff status.
• The complaints say an algorithm change at ODDITY’s largest ad partner pushed its ads into lower-quality auctions, which raised click prices and drove up customer-acquisition costs.
• ODDITY disclosed the disruption on February 25, 2026 and warned that first-quarter 2026 revenue would fall about 30% year over year.
• After that disclosure, the stock fell 49% to $14.74, and the suits seek damages under Sections 10(b) and 20(a) of the Exchange Act and Rule 10b-5.
